Types of Loft Extensions

Find the Perfect Solution for Your Home

Dormer Loft Conversion

A dormer loft conversion involves adding a vertical extension with a window to the existing roof, increasing usable space and bringing in more natural light. It’s a popular choice for those wanting to expand their loft and brighten the interior.

Mansard Loft Conversion

A mansard loft conversion reshapes the roof by raising the lower part of the roof and creating steep, almost vertical walls with a flat or shallow roof on top. This style maximizes space and is commonly used in traditional or period properties.

Hip to Gable Loft Conversion

A hip to gable conversion transforms a sloping, four-sided hip roof into a two-sided gable roof, significantly increasing the loft’s volume. This is ideal for homes with a hip roof wanting to add more headroom and floor space.

Open Loft Conversion

An open loft conversion creates a large, open-plan space in the loft without internal walls. It suits those who prefer spacious, airy interiors and a modern, loft-style design.

Bathroom Loft Conversion

A bathroom loft conversion adapts the loft into an additional bathroom, perfect for growing families or homes needing extra sanitary facilities.


Bedroom Loft Conversion

This conversion turns the loft into a bedroom, providing extra sleeping space without extending the property footprint. It often includes installing dormer windows or rooflights to improve comfort and lighting.

Studio Loft Conversion

A studio loft conversion transforms the loft into a multifunctional space combining living, working, and creative areas — ideal for artists, freelancers, or anyone needing a home office or creative studio.

We had our kitchen and bathroom completely remodeled and couldn’t be happier with the results. The workmanship is top-quality, and they really listened to our ideas. What stood out most was their attention to detail and how smoothly the whole process went. Will definitely use them again!

They turned our unused attic into a beautiful, functional home office with loads of natural light. Every part of the process was clearly explained, and the team was friendly, punctual, and very skilled. It feels like a whole new part of the house.

Fantastic experience from start to finish. The insulation work they did made a huge difference in our home’s comfort and energy efficiency. What impressed me most was how respectful and responsive they were throughout. It’s rare to find a company that truly cares.
